Opacity of the Atmosphere at Millimeter Wavelengths, Final Technical Report No. FTR-1
The theory of absorption by molecular oxygen in the wavelength region between 1 and 10 millimeters is summarized, and experimental methods of measuring atmospheric absorption are discussed. It is concluded that the agreement between experiment and theory is in general satisfactory. Short-period fluc...

Opacity of the Atmosphere at Millimeter Wavelengths, Final Technical Report No. FTR-1University of Alabama Research InstituteThe theory of absorption by molecular oxygen in the wavelength region between 1 and 10 millimeters is summarized, and experimental methods of measuring atmospheric absorption are discussed. It is concluded that the agreement between experiment and theory is in general satisfactory. Short-period fluctuations in atmospheric absorption, possibly correlated with variations in the earth's magnetic field or other external factors, have been suspected. The probable effects of time-varying external fields, Zeeman splitting, and statistical orientations of the oxygen molecule in the magnetic field are analyzed. None of these factors appear to explain the suspected variations.

The theory of absorption by molecular oxygen in the wavelength region between 1 and 10 millimeters is summarized, and experimental methods of measuring atmospheric absorption are discussed. It is concluded that the agreement between experiment and theory is in general satisfactory. Short-period fluctuations in atmospheric absorption, possibly correlated with variations in the earth's magnetic field or other external factors, have been suspected. The probable effects of time-varying external fields, Zeeman splitting, and statistical orientations of the oxygen molecule in the magnetic field are analyzed. None of these factors appear to explain the suspected variations. A limited experimental program is included in the study. |
